TRUCK.

SPECIFICATION forming part of Letters Patent No, 355,238, dated December 28, 1886.

'Application filed September 2, 1886. Serial No. 212,487. (No model.)

To all whom it may concern:

- Be it known that I, DANIEL S. \VING, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Trucks for Barrels, Boxes, and other 13Articles, of which the following is a specifica- This invention relates to certain improvements in trucks, as fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal vertical section in the plane so x,'Fig. 2. Fig. 2 is an inverted plan. Fig. 3 is a modification of the mechanism for actuating the clamping-levers. Figs. 4, 5, 6, and 7 are details, which will be referred to as the description progresses.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the platformor frame of a truck, which is provided with arms B B, and supported on wheels 0 O in such a manner that by means of the arms the frame can be brought into a horizontal or in an inclined position. If the truck is intended for a hand-truck, the arms B B form the handles; but if the truck is intended to be drawn by a horse or other animal, the arms B B form the thills, and in order to be able to operate the truck with the greatest possible convenience such thills will be made in two sections, connected by hinge-joints t, and provided with a locking device, a, as shown in Fig. 7. By means of such locking device the thills can be kept rigid; but if the locking device is released the outer sections of the thills can be turned down, as shown in Fig. 1,- while the frame or platform A is inclined.

On the frameAare secured the clampinglevers D D. Said levers swing on screw-studs a a, which are adjustablein slots a a, and they extend beyond the inner end of the frame and are provided with clamping jaws or grips b I). These grips may be made in the form of a single spur, (see Fig. 5,) or they may consist of india-rubber pads, (see Fig. 6,) or they. may be made with two or more spurs each and secured to the clamping-levers in such amanner that they can be rotated. (See Fig. 4.) The inner ends of the clamping-levers are bent, as shown in Figs. 2, 4, 5, and 6, so that when a large box is to be taken up which requires that the inner ends of the clamping-levers shall be spreadwide open, the bodies of these levers will not prevent the grips from taking hold of the box.

On the inner ends of the arms B B are firmly secured brackets B R, which carry the axles of the wheels 0 O, and which are connected by a cross-bar, S. This cross-bar is situated somewhat in advance of, but below, the inner edge of the platform or frame A.

The outer ends of the clampinglevers D D connect with a suitable mechanism for actuating the same. In the example shown in Figs. 1 and 2 of the drawings this mechanism consists of two toothed links or bars, E E, which are connected to the clamping-levers by pivots c 0, extending through curvedslots (1 d in the platform or frame A. Said links or bars engage teeth on a rotating disk or wheel, F, from opposite sides, being held in gear with said cog-wheel by studs 6 c.

On the cog-wheel is formed an outwardlyprojeeting flange, f, which prevents the bars from dropping out of gear with said cog-wheel. The toothed disk or wheel turns freely on the stud 9. On the toothed disk or wheel is firmly secured a lever, G, and by turning this lever in the direction of arrow 1, Fig. 2, the inner ends of the clamping-levers are caused to close up, whereas by turning. the lever G in the direction opposite to said arrow the clampinglevers are caused to open.

A spring, H, may be hitched to the disk or wheel F and to the frame A, which has a tendency to close up the clamping-levers. 1

In the modification shown in Fig. 3 the links or bars It E are pivoted adjacent to the periphcry of a rotary toothless disk or.wheel, F, carrying the lever G, so that the clamping-levers are operated by turning the disk through the medium of said lever.

W'ith the mechanism for actuating the clamping-levers is combined a locking mechanism for retaining the clamping-levers-i-n'their closed position. ings this lockingmechanism consists of a dog, I, which is firmly secured to the disk or wheel F or F, and which engagesa ratchet-segment, J. By forcing the outer end of the lever G slightly In the example s own in the draw- ICO upward the dog I is thrown out of gear with the ratchet-segment, so that the clamping-levers can be thrown open; but when the clampinglevers have been made to close upon a barrel or other article the dog I is thrown in gear with the ratchet-segment by the inherent gravity of the lever G, and the clamping-levers are locked in their closed position.

If the grips b I) take hold of the barrel or other article above or back ofits center of gravity,and said article is raised from the ground by depressing the arms B B, the cross-bar S forms a stop, which prevents the lower end of the barrel or other article from swinging inward beneath the platform or frame A; but if the grips take hold of the barrel or other article below or in front of its center of gravity the inner edge of the platform or frame A forms the stop, which prevents the barrel or other article from tipping over.

By adjusting the pivots a a of the clampinglevers in the slots aa the clamping ends of said levers can be adjusted to articles of different size.

5 What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a wheeled truckframe, of the pivoted clamping-levers, the centrally-pivoted rotary disk or wheel having an attached lever, .and links or bars pivoted at one end to the clamping-levers and at the other end portions engaging the rotary disk or wheel, substantially as described.

2. The combination, wit-h the wheeled truck- 5 frame having at each side a transverse slot, a,

of the clamping-levers D D, having pivots a, adjustable toward and from each other in the said transverse slots, and means for actuating 'the levers onsaid adjustable pivots, substantially as described.

3. The combination, with the wheeled truckframe having at each side a transverse slot, to, of the clamping-levers D D, having pivots a, adjustable towardand from each other in said transverse slots, a rotary disk or wheel pivoted to the truck-frame and having an attached lever, and links or bars pivoted at one end to the clamping-levers and at their other end portions engaging said rotary disk or wheel, substantially as described.

4. The combination, with a wheeled truckframe having an attached segmental rack, J, of the clamping-levers pivoted to the truck-frame, the rotary disk or wheel pivoted to the truckframe and provided with the attached dog I, and operating-lever G, and the links or bars pivoted at one end to the clamping-levers and at their other end portions engaging the rotary disk or wheel, substantially as and for the purposes described.

5. The combination, with the truck-frame and the wheels supporting the same, of the clamping-levers D D, the rack-bars E E, the cog-wheel F, and means for turning the cogwheel, substantially as described.

6. The combination, with the truck-frame and the wheels supporting the same, of the clamping-levers D D, the rack -bars E E, the cog-wheel F, the lever G, the dog I, and the ratchet-segment J, substantially as described.

7. The combination, with the truck-frame and the wheels supporting the same, of the clamping -levers D D, the rack -bars E E, the cog-wheel F, the lever G, and the spring H, substantially as described.

In testimony whereof I have hereunto set 'my hand and seal in the presence of two subscribing witnesses.
